If u are tank or melee dps u know how to hard avoid void zones on mimirion when 666 ppls +army of dead,pets,death and decay and other craps are on u.
Here is a little trick,when u use Baby Spices on phase 2 or phase 4(down part of boss) its very easy to see where rockets in melee area landing. And you'll dont get suprised by mine spawned under boss too,because when he is small he dont spawn it under him. Our melee always got oneshotted by rockets or bugged mines under boss animation,when we used that trick we one-shoted him.
Gl on kill.
